Section 20. Miscellaneous.



 (a) Severability, Amendment and Construction. Any provision of this Lease which is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof; and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction.

This Lease shall constitute an agreement of lease, and nothing herein shall be construed as conveying to Lessee any right, title or interest in the Aircraft or any Engine or Part except as a lessee only, and subject in all events to the terms and conditions hereof. The headings in this Lease are for convenience of reference only and shall not define or limit any terms of the provisions hereof. Whenever required by the context hereof, the singular shall include the plural and vice versa. All Exhibits and Schedules attached hereto are incorporated herein by reference and are deemed to be a part hereof.
